   Miss Scarlet and The Duke Season 4 Teasers from the Creator and Cast

   Want some insider secrets on what to expect in Season 4? There’s no better source than the cast and creator themselves! Learn what squeal-worthy secrets they had to share about what is ahead.

   Rachael New (Creator/Writer/Executive Producer): “Eliza’s got to decide: ‘Do I want to carry on in this kind of small business that I’m struggling with? Or do I want the weight and the clout of the most successful private detective agency in London behind me?’ That opens a box for her, like Pandora’s box.”

   When Arabella broke things off with the Duke at the end of Season 3 by pointing out his obvious feelings for Eliza, it was a “sharp kind of slap in the face” for the curmudgeonly Detective Inspector, said New. But the question remains: “Is [it] going to make him wake up and smell the coffee and realize that, you know, is it time to do something about [his feelings for Eliza]?”

   Kate Phillips (Eliza) : According to the leading lady of the series, there will be “more about Eliza and William’s history [and] how they came to be.” Plus, “There’ll definitely be some more fun characters for you to meet that are really great and you’ll just love them. And more sparring and back and forth than ever!”

   As for Eliza’s new job: “Nash & Sons allows her to meet lots of new people. She’s always looking to get one step ahead so the more people she meets, the more opportunities she has.”

   Stuart Martin (The Duke): “There’s a lot of revelations, a lot of the emotional stories are really pushed and tested,” Martin teased. “We get to see Eliza and Duke really move forward in their relationship.”

   Felix Scott (Nash): “Eliza and Nash get into a lot of trouble. That’s their thing, that’s their M.O.,” said Scott. “There’s a lot more running around, there’s a lot of capering which is going around which is lots of fun.”
